Describe the bug
Cannot use 'cp' command while installing it on Windows.
It is needed to replace 'cp' with 'copy' in scripts written in package.json if an user wants to install botfront on Windows machine.

To Reproduce
Steps to reproduce the behavior:

1. Install choco
2. Install meteor
3. Install botfront using meteor npm install in Windows Powershell.

Expected behavior

• A new botkit controller for Slack
• Updated HTML within ThirdParty/index.js
• At least boiler code for test suites.

Users misspell things. Having spell-check and synonyms helps a lot, but doesn't catch everything.

One solution would be to use the python metaphone package's implementation of the Double Metaphone algorithm.

At component train time, it could look at the normal entity lists, find the DM representation of all the synonyms, and store them.

Code here was demonstration of article in Analytics Vidhya, written in 2017. Over time RASA APIs have changed. So need to update code accordingly.
